PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000009267516

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along

with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain

types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS

system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front

air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SR and SB section of this Service Man-

ual.

WARNING:

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Instruction. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000009267517

When performing the procedure after removing cowl top cover, cover

the lower end of windshield with urethane, etc to prevent damage to

windshield.

Precaution for Brake System

INFOID:0000000009267518

WARNING:

Clean any dust from the front brake and rear brake with a vacuum dust collector. Do not blow with

compressed air.

• Brake fluid use refer to 

MA-12, "Fluids and Lubricants"

.

• Do not reuse drained brake fluid.

• Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off

immediately and wash with water if it gets on a painted surface.

• Always confirm the specified tightening torque when installing the brake pipes.

• After pressing the brake pedal more deeply or harder than normal driving, such as air bleeding, check each

item of brake pedal. Adjust brake pedal if it is outside the standard value.

< PRECAUTION >

PRECAUTIONS

• Always clean with new brake fluid when cleaning the brake caliper and other components.

• Do not use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and cause

improper operation.

• Always loosen the brake tube flare nut with a flare nut wrench.

• Tighten the brake tube flare nut to the specified torque with a crow-

foot (A) and torque wrench (B).

• Brake system is an important safety part. If a brake fluid leak is

detected, always disassemble the affected part. If a malfunction is

detected, replace part with a new one.

• Always connect the battery terminals when moving the vehicle.

• Turn the ignition switch OFF and disconnect the hydraulic booster

assembly harness connector or the battery negative terminal

before performing the work.

• Check that no brake fluid leakage is present after replacing the

parts.

• Burnish the brake contact surfaces after refinishing or replacing

rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
